After searching the internet with some of the suggestions provided here (per Freqman1). I searched “Asian Tricycle” and clicked on photos until I came across this posted on Etsy. The top tub is single, where mine is double, the fender setup is different and the front wheels are attached differently, but for the most part it looks the same. The header badge appears to say “Lion”, and under it “Made In Japan”. I believe it to be the same maker as the tricycle I have. I think it’s super neat.
I think the one I have is from the early to mid 70’s and the Etsy one is later 70’s - early 80’s. The colors may have been the same, but mine has faded to an orange ( areas under the head tube are still red). In the 70’s Japan was trying to develop more efficient manufacturing process and I think the changes in these bikes reflects those attempts. The Etsy bike looks like some attempts to lower costs.
Probably not many were purchased and probably less survived, so this will be a cool project. I’m going for a 70’s chopper/ moto theme.
